Mitigating Environmentally Assissted Cracking Through Optimisation of Surface Condition

Mitigating Environmentally Assissted Cracking Through Optimisation of Surface Condition

Objective

Environmentally-Assisted cracking (EAC) is one of the major failure modes occurring in light water reactors (LWRs). The condition of surfaces exposed to the primary coolant plays a main role on the susceptibility of components to EAC. However, many national and international guidelines and standards do not address surface condition of critical components in nuclear power plants (NPP)
The goal of the MEACTOS project is to improve the safety and reliability of Generation II and III of NPP by improving the resistance of critical locations, including welds, to EAC through the application of optimized surface machining and improved surface treatments.
MEACTOS is proposed by a consortium of 16 partners from 11 EU member countries (Spain, France, Finland, Czech Republic, Belgium, Germany, Slovakia, Romania, UK, The Netherlands and Slovenia) plus Switzerland (associated country of Euratom), that comprises all the appropriate key players to ensure the availability of technologies, capabilities, technical and operational knowledge required for the goal of the project. Research laboratories (VTT, SCK-CEN, CVR, CIEMAT, PSI, JRC, RATEN), universities (UNIMAN, STUBA) nuclear components suppliers (NAMRC, ENSA, SA.),utilities (EdF), engineering companies (ZAG, AMEC) and plant designers (AREVA-NP) has been selected in order to complete the required capacities to cover all the expertise fields faced by the project. The Consortium members have differential but complementary skills and expertise in areas such as project management, manufacturing, technology transfer or dissemination, to name a few key areas.

Pro-active material degradation programs outside Europe, particularly in Japan and in the United States, currently address, or plan to address, surface condition with respect to EAC. This European MEACTOS project will directly benefit Europe, engaging on an equal footing with these initiatives, maintaining a level of competitiveness for European industry in the global scenario.
